O33.9

Billable

Maternal care for disproportion, unspecified

This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).

What This Code Means

A pregnant woman receives care because her pelvis is too small or the baby is too large relative to the pelvis, but the specific type of disproportion is not documented.

Coding Tips

  • •Use this code only when the specific type of disproportion (cephalopelvic, fetal, maternal) is not specified in the documentation
  • •Review clinical notes to determine if a more specific O33 code (O33.0-O33.8) can be assigned instead
